Description

Technical Field

[0001] This utility model provides an environmentally friendly and energy-saving gas-fired multi-control ceramic plate grill, belonging to the field of grill technology. Background Technology

[0002] A barbecue grill is a cooking appliance, usually made of heat-resistant materials such as cast iron, stainless steel or ceramic, which has good thermal conductivity and durability. Barbecue grills can be divided into various types such as charcoal grill, gas grill and electric grill.

[0003] Currently, the most commonly used gas-fired grills on the market are those with ceramic infrared burners and side heating elements. The main structure of this type of grill includes: four ceramic infrared burners symmetrically arranged on the same horizontal plane, with their heating surfaces perpendicular to each other; two small DC 12V heat spreaders installed on the inner sides of the left and right sides of the grill; two gas valves installed on the front sides of the grill to control the heating surfaces of the burners facing each other; and an oil / water tank located below the burners. Currently, grills with ceramic infrared burners and side heating elements have the following disadvantages: 1. One gas valve distributes gas to two nozzles, which then supply a pair of... First, the gas supply to the two burners is uneven, resulting in inconsistent heat generation and uneven oven temperature, causing uneven burning. Second, existing gas ovens with ceramic infrared burners, regardless of oven size, are equipped with two sets of four burners controlled by different oven lengths. When only one gas valve is opened, half of the oven is working, which is wasteful and energy-inefficient when baking a small amount of food. Third, when the oven is 2 meters long, the length of a single burner is usually close to 85 centimeters. Combustion requires a sufficient amount of gas, but the natural gas supply is often insufficient, leading to abnormal combustion and unusable oven. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing ceramic plate infrared flame burner side heating devices for barbecue grills are not energy-efficient, have uneven grilling temperatures, and are not very practical.

[0005] To solve the above problems, the proposed technical solution is as follows: an environmentally friendly and energy-saving gas-fired multi-control ceramic plate grill, comprising a grill body; the grill body includes air source chambers respectively disposed on both sides, with air duct covers at both ends of the middle of the two air source chambers, with air duct front plates on the inner sides of the two air duct covers, and fire bars on the inner sides of the two air duct front plates, with a main gas pipe passing through one side air source chamber between the front air duct cover and the air duct front plate, with air distribution ducts between the front air duct front plate and the fire bars and between the rear air duct cover and the air duct front plate, with a speed-regulating fan in the middle of the outer side of the air source chamber, and pull-out oil and water tanks on both sides below the air duct covers, air duct front plates, and fire bars, with several gas valve handles and flow regulating valves on one side air duct cover.

[0006] As an improvement, the two air source chambers are hollow structures. The inner side of one air source chamber is connected to the air distribution duct, and the other air source chamber is connected to the first mixing chamber of the fire duct. The two speed-regulating fans control the wind speed through wind speed control controllers set above the front of the two air source chambers.

[0007] As an improvement, the two duct covers include a front duct cover and a rear duct cover. The front duct cover is divided into an upper cover and a lower cover, and several gas valve handles and flow regulating valves are set on the lower cover.

[0008] As an improvement, the upper part of the two air duct front plates is provided with a copper pipe that is connected to the main gas pipeline through a diffuser. The middle part of the copper pipe is provided with a gas valve that is connected to the flow regulating valve. The copper pipe is located on the side of the gas valve that is close to the main gas pipeline and is provided with a diversion valve. One end of the diversion valve is connected to the burner through the copper pipe through the air duct front plate.

[0009] As an improvement, several air distribution holes are provided on the lower inner side of the air distribution duct.

[0010] The beneficial effects of this utility model are:

[0011] This device features finely divided baking openings, allowing only the amount of baking required to be opened, thus saving energy.

[0012] The air required for combustion in the burner is supplied by a speed-regulating fan, so a wide range of gas pressure is required, making it highly practical.

[0013] The burner can ensure that the amount of gas obtained can be regulated by the flow regulating valve, ensuring that the same amount of gas is obtained, and it is easy to operate; Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] according to Figure 1 —4 shows: This utility model provides an environmentally friendly and energy-saving gas-fired multi-control ceramic plate grill: including a furnace body; the furnace body includes air source chambers 1 respectively disposed on both sides, with air duct cover plates 2 respectively provided at both ends of the middle of the two air source chambers 1, with air duct front plates 3 respectively provided on the inner side of the two air duct cover plates 2, and fire plates 4 respectively provided on the inner side of the two air duct front plates 3, with a main gas pipe 5 passing through one side air source chamber 1 between the front air duct cover plate 2 and the air duct front plate 3, and with air distribution ducts 6 respectively between the front air duct front plate 3 and the fire plates 4 and between the rear air duct cover plate 2 and the air duct front plate 3. A speed-regulating fan 101 is installed in the middle of the outer side of the air source chamber 1. Pull-out oil and water tanks 7 are respectively installed on both sides of the air duct cover 2, the air duct front plate 3, and the bottom of the burner 4. Several gas valve handles 201 and flow regulating valves 202 are installed on one side of the air duct cover 2. The baking port of this device is designed to be finely divided, and only the amount of gas is turned on, which is more energy-efficient. The air required for combustion of the burner 4 is provided by the speed-regulating fan 101, so a wide range of gas pressure is required. It is practical and the amount of gas obtained by the burner 4 can be adjusted by the flow regulating valve 202 to ensure that the same amount of gas is obtained. It is easy to operate.

[0020] according to Figure 2 As shown: The two air source chambers 1 are hollow structures. The inner side of one air source chamber 1 is connected to the air distribution duct 6, and the other air source chamber 1 is connected to the first mixing chamber of the fire duct 4. The speed of the two variable speed fans 101 is controlled by the speed control controller 102 located above the front of the two air source chambers 1. In this way, the output power of the variable speed fans 101 can be controlled by the speed control controller 102, so that the variable speed fans 101 on one side of the air source chamber 1 can provide different air volumes, and the variable speed fans 101 on the other side of the air source chamber 1 can achieve the function of air distribution.

[0021] according to Figure 2As shown: The two air duct covers 2 include a front air duct cover 203 and a rear air duct cover 204. The front air duct cover 203 is divided into an upper cover 205 and a lower cover 206. Several gas valve handles 201 and flow regulating valves 202 are set on the lower cover 206. In this way, the temperature generated by the burner 4 can be changed by the gas valve handles 201 and flow regulating valves 202 in conjunction with the speed regulating fan 101.

[0022] according to Figure 2 , 3 As shown: The upper part of the two air duct front plates 3 is provided with copper pipes 302 that are connected to the main gas pipeline 5 through diffusers 301. The middle part of the copper pipes 302 is provided with a gas valve 303 that is connected to the flow regulating valve 202. The copper pipes 302 are provided with a diversion valve 304 on the side of the gas valve 303 that is close to the main gas pipeline 5. One end of the diversion valve 304 is connected to the burner 4 through the air duct front plate 3 via the copper pipes 302. The lower inner side of the air equalization duct 6 is provided with several air equalization holes 601. In this way, the gas can be diverted and then pass through the air duct front plate 3 to reach the burner 4 for combustion.

[0023] The principle of this utility model is as follows: In use, the gas enters from the main gas pipeline 5, and then is diverted through the copper pipe 302 to the inlet of the gas valve 303. Then, one outlet of each group of gas valves 303 goes directly to the first mixing chamber of the burner 4, and the other outlet goes first to the flow regulating valve 202 and then to the diffuser 301 of the first mixing chamber of the burner 4. The air required for combustion of the burner 4 comes out from the air source chamber 1 on one side of the furnace body to the front and rear equalization air ducts 6, and is then supplied to the front and rear burners 4 of each group by the front and rear equalization air ducts 6. The combustion temperature of the burner 4 is determined by the amount of gas and air supplied. Then, the air coming out of the equalization air hole 601 sends part of the heat generated by the burner 4, which is vertically installed directly below the equalization air hole 601, to the middle of the baking opening, so that the temperature of the baking opening is uniform. The width of the baking opening requires different equalization air volume, which is provided by the speed regulating fan in the equalization air source chamber.
